We characterize the intensity of innovation by a sales-weighted measure of innovation: the share of sales in innovative products, but other output indicators of innovation could be considered as well. Comparing statistics on the share of innovative sales across countries, industries, or firms measures but does not explain the intercountry, interindustry, or interfirm differences in innovation intensity. To have a more meaningful basis of comparison we need a model. If an exact model of innovation in its various dimensions existed and if we knew it, we would be able to understand fully why innovation differs among countries, industries, or firms. Of course, such a model does not exist. Nevertheless it is worth trying to account for innovation differences, if only very roughly. In such an endeavor, what remains to be explained is as important to consider as what can be explained, because it reflects the extent of innovative ability or capacity, or “innovativeness.” To motivate our approach better and make it more explicit, we find it appealing to draw a comparison with the standard framework for growth accounting and the
